Aurizon Mines Ltd. notched an $18 million gross profit in the first quarter of 2011, bettering Q1 of 2010 by 43%. The Toronto-listed miner chalked up $14.5 million in cash flow from operations, a 58% increase from the same period last year. The company says its results were positively impacted by rising operating profit margins, and offset by increased exploration at its exploration properties. Revenue from its Casa Berardi operation increased, from $39.8 million in the first quarter of 2010, to $47.2 million in Q1 of 2011, on higher gold prices. Image by Aurizon Mines

The gold-silver ratio (GSR) measures how many ounces of silver one can purchase for an ounce of gold, on a certain date. Reference to the ratio has a long history. One of the first mentions was that upon the death of Alexander the Great, the ratio was 12.5 to 1. During the Roman Empire, the ratio was set at 12. By the late 19th century, the ratio had risen to 15. Interestingly, these historical ratios roughly reflect geologists’ estimates that silver is 17 times more abundant than gold in the earth’s crust. This gives many investors a reason to believe that 17 is the natural balance between these elements, and that eventually the GSR will return to it.
